EBIEECIFIGATION forming part of Letters Patent No. 307,670, datedNovember 4, 1884.

Applicaiion filed May 27, 1884.

T0 aZZ whom it may concern: 1

Be it known that I, J. F. MOKINLEY, of River Bridge, in the county ofMonroe and State of Alabama. have invented certain new and usefulImprovements in Flows; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in plows; and it consists in thecombination of the slotted metallic standard, mold-board, and slide,which is provided with a part which catches over the top of themold-board and holds it rigidly in place, and the clampingbolt, as willbe more fully described herein after.

The object of my invention is to clamp the mold-board to the slottedstandard by a single bolt, and to pass this bolt through a device whichcatehes both against the rear of the standard and over the top of themoldboard, so as to hold the niold-bord rigidly in position.

Figure l is a front view of a plow embody ing myinvention. Fig. 2 is aside elevation of the same. Fig. 3 is a perspective of theJtLzlamping-plate by which the mold-board is ield.

A represents the beam, B the slotted stand ard, G the brace which isattached to the lower end of the standard, and which has its upper endto pass up through the rear end of the beam A. The mold-board is appliedto the front side of the standard in the usual manner, and only a singleclamping-bolt, F, is used to clamp it in place. In order to pre ventthis mold-board from turning upon the bolt, the clamping-slide G isused, which is applied to the rear side of the standard, as

(No model.)

I shown, and through which the clamping-bolt passes. Projecting from theupper end of this slide is the arm I, and upon the front end of this armis formed the cross-bar J. This arm is just long enough to pass throughthe standard and the bar J, which extends over the upper edge of themold-board, as shown, so as to prevent the nioldboard from turning uponthe bolt. This plate has its edges (6 turned at right angles to itscentral portion, so as to catch over the opposite edges of the standard,and thereby prevent the plate itself from having any tendency whateverto turn. Alter the bolt has been passed through the n10ld-b0ard, thestandard, and the clampingplate the nut is secured tightly upon its rearend, and the plate will then hold the moldboard rigidlyin place. Bymeans of this construction not only is the mold-board held by a singlebolt, butit can be adjusted up and down upon the standard at the will ofthe operator an 1 with very little trouble.

I am aware that various forms of devices have been used to catch overthe top edge of the cultivator; but in no case has a slotted platehaving flanges on its edges to catch over the sides of the standard, anarm to extend through thestandard, and a downturned flange on its frontend, been used.

Having thus described my invention, I claim- The combination of thedouble standard, the slotted slide G, having the fllanges a, the arm I,and downturned flange J, the bolt F, and the mold-board, substantiallyas shown.

In testimony whereof I affiX my signature in presence of two witnesses.
